written, as in many reviews the jack is built very robust and stable. However, a rubber pad in my opinion is needed. Am not find anything on Amazon. In the catalog of 2012 by Kunzer is the item number "WK04866" that fits on the jack (to fit) Do I need to try however even once (just been ordered from Ebay) for 23,40 incl. Shipping. Not cheap for just a rubber pad before it is invested a lot of time but so much the better.
